SUMMARY

Below is a description of the Farallon LocalTalk PC network card.

The following are the system requirements (according to the owner's guide):

  • IBM PC or compatible with at least 256K of RAM
  • Two floppy disk drives or one floppy disk drive and a hard drive
  • Microsoft MS-DOS or IBM PC-DOS version 3.1 or later
  • LocalTalk Locking Connector Kit (DB-9)
The following are the default DIP switch settings for the Apple LocalTalk PC network card: 
  Switch  Desc   Default   Function
   ------------------------------------------------------------------

   1       IRQ4     Off     Selects Interrupt Request level 4. Same
                            interrupt as serial port COM1. Switches 2
                            and 3 must be off to select IRQ4.

   2       IRQ3     On      Selects Interrupt Request level 3. Same as
                            serial port COM2. Switches 1 and 3 must be
                            off to select IRQ3.

   3       IRQ2     Off     Selects Interrupt Request level 2. This
                            setting must not be used on a PC/AT
                            machine because it conflicts with the hard
                            disk controller. Switches 1 and 2 must be
                            off to select IRQ2.

   4,6  DRQ3,DACK3  Off     DMA Request and DMA Acknowledge on DMA
                            channel 3. Both switches must be on (and
                            switches 5 and 7 off).

   5,7  DRQ1,DACK1  On      DMA Request and DMA Acknowledge on DMA
                            channel 1. Both switches must be on (and
                            switches 4 and 6 off).

   8    $24x/$22x   On      Selects the address range of the card. If
                            this switch is on, the card will respond
                            to control signals sent to addresses in
                            the range $240 through $247. If this
                            switch is off, the card will respond to
                            control signals sent to addresses $220 to
                            $227.
If you change the DIP switch settings on the card to resolve any conflicts with other cards in your system, you must notify the AppleTalk driver ATALK of these changes. This is done by adding one or more parameters after the driver name ATALK.COM. The following table summarizes these options: 
   Option       Default     Other Possible Values
   ------------------------------------------------------------------

   /CARDINT=x      3               2 or 4
   /DMA=x          1           3 (PC/AT only)
   /ADDRESS=xxx   $24x               220
